Description

Technical Field

[0001] This utility model relates to a support section assembly for a slide rail, belonging to the field of slide rail technology. Background Technology

[0002] Current three-section slide rails include an outer slide rail, a middle slide rail, and an inner slide rail. Taking a chassis-type server as an example, the outer slide rail is fixed to the rack, the inner slide rail is fixed to both sides of the compute tray or power supply tray, and the middle slide rail is set between the outer and inner slide rails as a load-bearing rail to extend the tray's range of motion. Furthermore, the inner and middle slide rails can slide back and forth relative to each other along the outer slide rail, allowing the tray to be freely pulled out or retracted. However, existing liquid-cooled rack slide rails suffer from a mismatch between their length and the rack's length. Summary of the Invention

[0003] The purpose of this invention is to provide a support section assembly for a slide rail, which can improve the installation accuracy and versatility, as well as the positional accuracy and convenience during assembly with the frame.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a support section assembly for a slide rail, comprising: an outer rail body and an inner rail body stacked within the outer rail body; one end of a first support body is embedded between the outer rail body and the inner rail body and fixedly connected to the outer rail body and the inner rail body; the other end of the first support body extends to the outside of one end of the outer rail body and the inner rail body and is used for mounting connection with a frame; one end of a second support body is located outside the other end of the outer rail body and the inner rail body and is used for mounting connection with a frame; the other end of the second support body is slidably embedded between the outer rail body and the inner rail body; the second support body has at least one strip-shaped hole extending along its length direction, which is connected to the strip-shaped hole. A connecting post corresponding to the shaped hole passes through the shaped hole and connects to the outer rail and the inner rail respectively. The outer rail has a clearance through hole that extends in the same direction as the shaped hole. A first hook portion formed on the second support passes through the clearance through hole and connects to one end of an elastic member. The other end of the elastic member, which extends along the length of the second support and is in a stretched state, is connected to the second hook portion formed on the outer rail. When the second support is in the first position, the connecting post is located at one end of the shaped hole and the stretching length of the elastic member is the shortest. When the second support is in the second position, the connecting post is located at the other end of the shaped hole and the stretching length of the elastic member is the longest.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the connecting post is a rivet stud that is riveted to the outer rail body and the inner rail body at both ends respectively, and the connecting post is clearance fitted with the inner wall of the strip hole on the second support body.

[0006] 2. In the above scheme, the four or six strip holes are arranged in two columns along the length of the second support.

[0007] 3. In the above scheme, the first hook portion on the second support body is located on the side of the second hook portion closer to the first support body. When the second support body is in the first position, the connecting post is located at the end of the strip hole closer to the first support body and a travel interval is formed between the second support body and the first support body.

[0008] 4. In the above scheme, the length of the stroke interval is the same as the length of the strip hole.

[0009] 5. In the above scheme, the first hook portion on the second support body is located on the side opposite to the first support body. When the second support body is in the first position, the connecting post is located at the end opposite to the first support body of the strip hole and the second support body is in contact with the first support body.

[0010] 6. In the above scheme, the first support body is fixed to the outer rail body and the inner rail body by riveting.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The support section assembly of the slide rail of this utility model has at least one strip-shaped hole extending along its length on the second support body. A connecting post corresponding to the strip-shaped hole passes through the strip-shaped hole and is connected to the outer rail body and the inner rail body respectively. The outer rail body has a clearance through hole in the same direction as the extension of the strip-shaped hole. A first hook portion formed on the second support body passes through the clearance through hole and is connected to one end of an elastic member. The other end of the elastic member, which extends along the length of the second support body and is in a stretched state, is connected to the second hook portion formed on the outer rail body. When the second support body is in the first position, the connecting post is located at one end of the strip-shaped hole and the stretched length of the elastic member is the shortest. When the second support body is in the second position, the connecting post is located at the other end of the strip-shaped hole and the stretched length of the elastic member is the longest. The overall length can be adjusted by the telescopic movement of the second support body to compensate for length deviations during installation and to adapt to frames of different sizes, thereby improving the installation accuracy and versatility. The positional accuracy and convenience during the assembly process with the frame can also be improved by the cooperation of the elastic member. Attached Figure Description

[0015] Example 1: A support section assembly for a slide rail includes: an outer rail body 2 and an inner rail body 1 stacked within the outer rail body 2; one end of a first support body 3 is embedded between the outer rail body 2 and the inner rail body 1 and is fixedly connected to the outer rail body 2 and the inner rail body 1; the other end of the first support body 3 extends to the outside of one end of the outer rail body 2 and the inner rail body 1 and is used for mounting connection with a frame; one end of a second support body 4 is located outside the other end of the outer rail body 2 and the inner rail body 1 and is used for mounting connection with a frame; the other end of the second support body 4 is slidably embedded between the outer rail body 2 and the inner rail body 1; the second support body 4 has at least one strip-shaped hole 5 extending along its length direction, and a connecting post 6 is provided corresponding to the strip-shaped hole 5. The connecting post 6 passes through the strip hole 5 and is connected to the outer rail body 2 and the inner rail body 1 respectively. The outer rail body 2 has a clearance through hole 7 that extends in the same direction as the strip hole 5. A first hook part 81 formed on the second support body 4 passes through the clearance through hole 7 and is connected to one end of an elastic member 9. The other end of the elastic member 9, which extends along the length direction of the second support body 4 and is in a stretched state, is connected to the second hook part 82 formed on the outer rail body 2. When the second support body 4 is in the first position, the connecting post 6 is located at one end of the strip hole 5 and the stretched length of the elastic member 9 is the shortest. When the second support body 4 is in the second position, the connecting post 6 is located at the other end of the strip hole 5 and the stretched length of the elastic member 9 is the longest.

[0016] The connecting post 6 is a rivet stud that is riveted to the outer rail body 2 and the inner rail body 1 at both ends respectively. The connecting post 6 is clearance-fitted with the inner wall of the strip hole 5 on the second support body 4. The four strip holes 5 are arranged in two rows along the length of the second support body 4. The first hook portion 81 on the second support body 4 is located on the side of the second hook portion 82 close to the first support body 3. When the second support body 4 is in the first position, the connecting post 6 is located at the end of the strip hole 5 close to the first support body 3 and a travel interval is formed between the second support body 4 and the first support body 3. The length of the above-mentioned travel interval is the same as the length of the strip hole 5.

[0017] Example 2: A support section assembly for a slide rail includes: an outer rail body 2 and an inner rail body 1 stacked within the outer rail body 2; one end of a first support body 3 is embedded between the outer rail body 2 and the inner rail body 1 and is fixedly connected to the outer rail body 2 and the inner rail body 1; the other end of the first support body 3 extends to the outside of one end of the outer rail body 2 and the inner rail body 1 and is used for mounting connection with a frame; one end of a second support body 4 is located outside the other end of the outer rail body 2 and the inner rail body 1 and is used for mounting connection with a frame; the other end of the second support body 4 is slidably embedded between the outer rail body 2 and the inner rail body 1; the second support body 4 has at least one strip-shaped hole 5 extending along its length direction, and a connecting post 6 is provided corresponding to the strip-shaped hole 5. The connecting post 6 passes through the strip hole 5 and is connected to the outer rail body 2 and the inner rail body 1 respectively. The outer rail body 2 has a clearance through hole 7 that extends in the same direction as the strip hole 5. A first hook part 81 formed on the second support body 4 passes through the clearance through hole 7 and is connected to one end of an elastic member 9. The other end of the elastic member 9, which extends along the length direction of the second support body 4 and is in a stretched state, is connected to the second hook part 82 formed on the outer rail body 2. When the second support body 4 is in the first position, the connecting post 6 is located at one end of the strip hole 5 and the stretched length of the elastic member 9 is the shortest. When the second support body 4 is in the second position, the connecting post 6 is located at the other end of the strip hole 5 and the stretched length of the elastic member 9 is the longest.

[0018] The six strip-shaped holes 5 mentioned above are arranged in two rows along the length of the second support 4; The first hook portion 81 on the second support body 4 is located on the side opposite to the second hook portion 82 of the first support body 3. When the second support body 4 is in the first position, the connecting post 6 is located at the end of the strip hole 5 opposite to the first support body 3 and the second support body 4 and the first support body 3 are in contact (not shown in the attached figure). The first support 3 is fixed to the outer rail 2 and the inner rail 1 by riveting.

[0019] In use, the support section assembly is fixedly installed on the rack and cooperates with other slide rail sections for connection with the cabinet box to realize the pull-out between the cabinet box and the rack. This application only involves the improvement of the support section. Other slide rail sections can be selected from mature solutions in the prior art, which will not be elaborated here. When installing the support section assembly of this application, the first support body is first fixed to the frame by bolts or other locking methods. The second support body is kept in the initial state of being closest to or furthest from the first support body under the action of the elastic element, that is, the shortest or longest state within the adjustable range of the support section assembly. Then, according to the size of the frame, the length of the second support body embedded in the outer rail and inner rail is adjusted to match the length of the cabinet. During the sliding adjustment of the second support body, the force generated by the elastic element needs to be resisted, which makes it easy for one person to operate with one hand and can also improve the final positional accuracy of the second support body installed on the frame.

[0020] When using the support section assembly of the above-mentioned slide rail, the second support body 4 has at least one strip-shaped hole 5 extending along its length direction. The connecting post 6, which is provided corresponding to the strip-shaped hole 5, passes through the strip-shaped hole 5 and is connected to the outer rail body 2 and the inner rail body 1 respectively. The outer rail body 2 has a clearance through hole 7 that is consistent with the extension direction of the strip-shaped hole 5. A first hook part 81 formed on the second support body 4 passes through the clearance through hole 7 and is connected to one end of an elastic member 9. The other end of the elastic member 9, which extends along the length direction of the second support body 4 and is in a stretched state, is connected to the outer rail body 2. The second hook part 82 is connected. When the second support body 4 is in the first position, the connecting post 6 is located at one end of the strip hole 5 and the stretching length of the elastic element 9 is the shortest. When the second support body 4 is in the second position, the connecting post 6 is located at the other end of the strip hole 5 and the stretching length of the elastic element 9 is the longest. The overall length can be adjusted by the telescopic movement of the second support body 4 to compensate for the length deviation during the installation process and to adapt to different sizes of frames, thereby improving the installation accuracy and versatility. The positional accuracy and convenience during the assembly process with the frame can also be improved by the cooperation of the elastic element.
